Requirement of the Escherichia coli dnaK gene for thermotolerance and protection against H2O2.

Journal of general microbiology - 1 Oct 1990

Delaney J M

Abstract excerpt

Thermotolerance in Escherichia coli is induced by exposing cells to a brief heat shock (42 degrees C for 15 min). This results in resistance to the lethal effect of exposure to a higher temperature (50 degrees C). Mutants defective in the recA, uvrA and xthA genes are more sensitive to heat than the wild-type. However, after development of thermotolerance these mutants are like the wild-type in their heat...
